There are performance.... I'm sorry to interrupt you; yes, there are. There have been established thresholds for railcar cycle time and dwell time and such other things that really affect the efficiency of the system.
I think our principal goal, from a port authority standpoint, has been to determine exactly where the pinch points are and what the inefficiencies are in discharging cars and loading vessels quickly, so that in our capacity as a port authority we can do what we can do to try to reduce or eliminate those pinch points. It could be infrastructure investments or it could be regulatory changes to provide for more efficiency in the system.
That's one of our principal objects—being able to measure how efficiently the system is operating as opposed to penalizing the railways.
